I applied through a recruiter. The process took 1 day. I interviewed at Amazon (Boston, MA) in Dec 2011
Interview
This was a recruiting drive. I was contacted by email and asked if I wanted to participate in a recruiting drive in Boston. I had 4 hour long interviews one right after the other at a hotel. Amazon had rented out a suit of conference rooms for the event. The interviewers were pleasant, and seem to have a set of questions (or types of question) that they asked. Each interviewer seem to focus on different things. The interview process was very STAR (situation, task, action, result) oriented. Look this up in the web, it's worth it.
After the question, you were given a problem to work on. The problems are not difficult, just take your time and talk it out. Talking through the problem is really important since it can save you from going down the wrong path.
Interview questions [1]
Question 1
There was nothing especially difficult. I'm not allowed to discuss the specific problems but I will give some general answers. There were a couple of cute problems, but mainly the problems were related to searching some space. I had 2 problems that required breadth first searches. A problem which looked more difficult than it was. This is probably the hardest type of problem, because it requires that you think about it and play with it until you see the simple solution. Think out loud, this is important.
Interview by recuriter, Phone interview over Chime with one easy Leet code problem and 2 behavioral questions. Although the interviewer was very casual at the start of the conversation, it quickly changed into behavioral questions at the start.

Question 1
Encoding optimization algorithm and talk about a project you did recently.
First round is just leet code coding which screens through AI before going into live coding. Pretty simple and straighforward. Not too tough. Recruiter walks through it pretty nicely. Not sure how many rounds there are exactly
After submitting my application for the Software Engineer position, I received an invitation to complete an automated Online Assessment (OA). The assessment consisted of standard coding challenges, primarily focusing on algorithmic and data structure problems. Unfortunately, a few days after submitting my solutions for the assessment, I received an email informing me that I would not be moving forward in the interview process and was rejected.
